Abstract
The utility model relates to a multi -core optical distribution cable, including the sheath, set up enhancement layer in the sheath, and set up enhancement core in the middle of the enhancement layer, strengthen being provided with many single core optical fiber between core and the enhancement layer. The utility model discloses enhancement layer inlayer and skin all are provided with the metal mesh, can improve indoor fiber optic cable's mechanical properties and environmental performance.
Description
Technical field
This utility model is related to a kind of optical cable and in particular to a kind of Multi-core optical distribution cable.
Background technology
By the use of optical fiberss as the fiber optic communication of the transmission medium of light, why can obtain in decades rapidly at this
Development, is that to have (1) transmission frequency bandwidth, message capacity big due to it；(2) decay is little；(3) it is not subject to the outstanding advantages such as electromagnetic interference
And determine, but light itself is fragile, and the low defect of mechanical strength requires it must be set with protection shell composition in outer layer
Optical cable to provide mechanical protection for it, the basic demand to protection shell is: ensure manufacturing, lay, use during light
Fibre does not rupture, and suffered stress is little；The original transmission performance of optical fiber must be kept in the fabrication process, and ensure that optical fiber exists
During life-time service, transmission performance is reliable and stable.
The inside cable structure being usually used at present is relatively simple, by single tight tube fiber and be coated on single tight tube fiber
The restrictive coating on surface is constituted, and the production technology of this inside cable is relatively simple, but the mechanical performance of interior optical cable is poor, makes
With during be easily caused bending or the fracture of optical fiber, lead to the transmission of optical signal to lose or interrupt.
In view of above-mentioned defect, the design people, actively research and innovation in addition, to founding a kind of multicore of new structure
Optical distribution cable is so as to more the value in industry.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of Multi-core optical distribution cable.
The technical solution of the utility model is as follows:
A kind of Multi-core optical distribution cable it is characterised in that: include sheath, be arranged on the enhancement layer in described sheath, Yi Jishe
Put the strengthening core in the middle of described enhancement layer, between described strengthening core and enhancement layer, be provided with many single-core fibers；Described reinforcement
The internal layer of layer and outer layer are provided with wire netting；The thickness of described wire netting is 0.8～1.0mm.
Further, described enhancement layer is made for highstrenghtpiston.
Further, described strengthening core is metal tube.
By such scheme, this utility model at least has the advantage that
This utility model enhancement layer internal layer and outer layer are provided with wire netting, it is possible to increase the mechanical performance of inside cable and
Environmental performance.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed
Describe in detail bright as after.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.
Referring to Fig. 1, a kind of Multi-core optical distribution cable described in this utility model one preferred embodiment, including including sheath 1, arrange
Enhancement layer 3 in described sheath 1, and it is arranged on strengthening core 4, described strengthening core 4 and the enhancement layer 3 in the middle of described enhancement layer
Between be provided with many single-core fibers 5.
The internal layer of enhancement layer 3 described in this utility model and outer layer are provided with wire netting 2.
In this utility model, enhancement layer is made for highstrenghtpiston.
In this utility model, strengthening core is metal tube.
In this utility model, the thickness of wire netting is 0.8～1.0mm.
The above is only preferred implementation of the present utility model, be not limited to this utility model it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, can also do
Go out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
